Contagious Love by Cassidy James

Elise Bordeaux is a successful history professor at a top university, with her second book about to be published. So why does it feel like her life’s falling apart when she catches her fiance cheating? She flees to her parent’s beach house in Delaware to pull herself together.
Jack Huntington is crushed when he finds out his wife has been having an affair and plans to leave him. Needing a break from California, he takes an architectural commission from an old family friend to spend a few weeks by the beach and clear his head.
Teenage sweethearts Elise and Jack met on the beach in Delaware and fell in love during a long hot summer, but when Jack let Elise down, she swore to never see him again. Little do they know that they are about to be trapped together for weeks during lockdown. As they begin to feel the heat rise, they have to decide – is this just a rebound or has love rekindled?
